This is a colorful, large format map of Colorado at the end of the 19th century detailing the Geology of the state. The map was published as part of Hayden's "Geological and Geographical Atlas of Colorado and Portions of Adjacent Territory."
As one can assume, the geologic makeup of Colorado is quite varied in age and composition. A key at the top right helps to identify the various layers including Tertiary, Post Cretaceous, Cretaceous, Silurian, Metamorphic, and Eruptive Rocks, to name a few. In all the map gives new meaning to the nickname "Colorful Colorado."
Nicknames for various area in the Rockies are given along with the elevation of many of the highest peaks. Rivers and their tributaries can be traced throughout, some of which will lead you to old mining towns that came and went. Early wagon trails and railroads snake their way from end to end of the map.
Ferdinand Hayden, known to the Sioux as "man-who-picks-up-stones-running" was one of the most important geologists of the 19th Century. From the 1853 - 1878 he provided the United States government and land speculators with vital information pertaining to the American West and was an instrumental figure in the founding of the world's first national park, Yellowstone.
